Hi,
I'm playing Volt White 2 and the in-game trade on Route 7 isn't working (trading Torkoal for Gengar).
The guy says he wants to trade Torkoal for Gengar, but doesn't accept my Torkoal.
When I trade him an Emolga (the trade in the original game), he accepts and gives me a Gigalith nicknamed "Gengar".
I haven't tried the other trades yet.
